Re: Why I can't have primary key on field that has index?

create table t1(
f1 integer constraint f1_index primary key disable; f2 integer not null)l
commit;
create index f1_index on t1(
f1);
commit;
alter table t1 enable primary key;
commit;

primary keys are by definition not null and unique! HTH
